Curriculum Associates Expands Partnership with MetaMetrics® to Provide Quantile® Measures for i-Ready®

Curriculum Associates Delivers Actionable Math Metric through the Use of the Quantile Framework

DURHAM, NC, — Curriculum Associates now offers educators a valid and reliable measure of student mathematical readiness to help educators monitor student growth and differentiate instruction in mathematics. The company has expanded its partnership with MetaMetrics, developer of The Quantile® Framework for Mathematics, to provide Quantile measures in their popular i-Ready® Diagnostic & Instruction product. Curriculum Associates partnered with MetaMetrics in 2012 to add Lexile® measures to i-Ready, a nationally recognized online assessment and instruction program. Now reporting Quantile measures, i-Ready provides a seamless K-8 experience for educators to measure and track student progress in mathematics. 

Built for the Common Core State Standards in reading and mathematics, i-Ready Diagnostic & Instruction combines a K-12 online student assessment, K-8 online interactive lessons and teacher-led instruction, and mobile apps for purposeful practice, into one comprehensive solution. It is designed to help students who are struggling and need remediation as well as those on-level students who need reinforcement, and those who need additional academic challenges. i-Ready has been implemented nationwide and has been state-approved program in NY, CO, GA, OK, OH, VA, and UT. Through its adaptive, diagnostic assessments and easy-to-use reports, i-Ready provides Quantile measures for students in kindergarten through 8th grade.

“i-Ready is a proven success in classrooms across the nation. With the greater emphasis on the Common Core, I applaud Curriculum Associates for their leadership in providing educators with an essential tool to support successful implementation of the Common Core State Standards,” said MetaMetrics’ President and Co-founder Malbert Smith III, Ph.D. “By linking i-Ready with the Quantile Framework, not only is Curriculum Associates delivering a valuable math metric and a tool for differentiated instruction, but they are also at the forefront of emphasizing the importance of mathematics.”  

Quantile measures help improve mathematics teaching and learning by helping teachers target instruction and monitor student growth toward proficiency standards and the mathematical demands of college and careers. Educators and parents can access free, targeted resources on including more than 580 textbooks, 64,000 lessons and 3,100 downloadable resources that are aligned with the Quantile scale. 

“We are thrilled to now report Quantile measures, in addition to Lexile measures, on i-Ready,” said Curriculum Associates’ CEO Rob Waldron. “Similar to the Lexile Framework, the Quantile Framework provides the means for educators to connect students with the appropriate material that engages students and supports growth in math. The Quantile measures in i-Ready greatly contribute to our mission to deliver an effective learning platform that focuses on students meeting the math demands of the Common Core State Standards.”

The Quantile Framework for Mathematics is a unique measurement system that uses a common scale and metric to assess a student’s mathematical achievement level and the difficulty of specific skills and concepts. The Quantile Framework describes a student’s ability to solve mathematical problems and the demand of the skills and concepts typically taught in kindergarten mathematics through Algebra II, Geometry, Trigonometry and Precalculus. Quantile measures take the guesswork out of instruction by describing which mathematical skills and concepts the student has learned and is ready to learn.
